NEET Physics Question - Current Electricity

Assertion (A): When identical cells are connected in parallel to the external load, the effective emf increases.

Reason (R): All the cells will be sending unequal current to the external load in the same direction.

Both (A) & (R) are true and the (R) is the correct explanation of the (A)

Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(A) is true but (R) is false

Both (A) and (R) are false

Solution:

When identical cells are connected in parallel, the effective EMF remains the same as that of a single cell, while the current capacity increases. Thus, Assertion (A) is false. For identical cells, current distribution should be equal. Thus, Reason (R) is also false.
